Construction of portable device for fast analysis of energetic materials is described in this paper. The developed analytical system consists of two main parts: a miniaturized microcolumn liquid chromatograph of unique construction and original chemiluminescence detector. This novel portable device is able to determine selectively most of nitramineand nitroester-based explosives as well as inor...

We examine the use of read-time feature conditionals, with particular emphasis on writing portable Common Lisp code which aspires to both forwardsand backwards-compatibility. We examine cases from real libraries which demonstrate the various pitfalls, and propose a scheme for robust treatment of implementation-specific functionality by performing programmatic tests at the appropriate time. We d...

Computers are deterministic devices and a computer-generated random number is a contradiction in terms. As a result, computer-generated pseudorandom numbers are fraught with peril for the unwary. We summarize much that is known about the most well-known pseudorandom number generators: congruential generators. We also provide machine-independent programs to implement the generators in any langua...

■ Social—With increasing attention on health and technological progress both home and abroad, home health care engineering (HHCE) is an emerging discipline. It advocates the concepts of medical treatment at home, self health care, and remote diagnosis, and combines technology with medical treatment. While addressing the trends of an aging society, soaring medical expenses, and increasing health...

Self-propagating abnormal proteins, prions, have been identified in yeast; asparagine/glutamine-rich 'prion domains' within these proteins can inactivate the linked functional domains; new prion domains and reporters have been used to make 'synthetic prions', leading to discoveries of new natural prions.

The recent parallel language standard for shared memory multiprocessor (SMP) machines, OpenMP, promises a simple and portable interface for programmers who wish to exploit parallelism explicitly. In this paper, we present our effort to develop portable compilers for the OpenMP parallel directive language. Our compiler consists of two parts. Part one is an OpenMP parallelizer, which transforms s...

We present the design and implementation of a highly portable multi-antenna datalogging system which can log several minutes of multi-channel raw GPS L1 baseband. In addition, our design interleaves two serial data streams with the baseband data, allowing, e.g., inertial data to remain synchronized with the data stream. The system is FPGAbased and uses two CompactFlash cards for storage. The da...
